3 Claims.

This invention relates to an indicator for a jacquard box loom, the general object of the invention being to provide means to raise the box vibrator of a loom in perfect time in connection with the cam of the vibrator levers, insuring the up or down movement of the vibratory lever at the proper time.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described and claimed in the accompanying drawings, and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views and in which:--

Figure 1 is a view showing the invention in use.

Fig. 2 is an elevation of the invention showing a pair of the improved assemblies with the parts of one assembly in a diiferent position from those of the other.

Fig. 3 is a similar view but showing but one assembly with the parts in a position to lift the vibratory lever.

Fig. 4 is a section on the line 4.-4-. of Fig. 3.

Fig. 5 is a section on the line 55 of Fig. 3.

Fig. 6 is a view looking towards the left-hand side of Fig. 3.

Fig. 7 is a view looking towards the right hand side of Fig. 3.

Fig. 8 shows a side view and an end view of one of the hook levers and its operating lever.

Referring to the drawings, the numeral 1 indicates a supporting frame which is attached to a part 2 of the loom. This frame 1 supports the assemblies of levers, but as all the assemblies are the same, but one will be described.

A horizontal lever 3 is pivoted intermediate its ends to the lower part of the frame, and a bell crank lever 4 is pivoted to the frame, the hori- Zontal part of the lever being forked as shown at 4 and the upper end of a link 5 and a hook lever 6 are pivotally connected between the prongs of the fork as shown at 7. The lower end of the link 5 is adjustably connected to the lever 3 by means of a bolt or screw 8 which is adapted to engage any one of a number of holes 9 in said lever 3. The hook of the lever 6 is shown at 10 and a spring 11 connects the free end of the lever 6 with a bolt 12 on the frame which passes also through a slot 13 in an adjustable stop 14 which limits the downward movement of the bell crank.

A slotted plate 15 extends at right angles from the frame and the lever 6 passes through the slot 16 in said plate and the lever 3 passes through the slot 17 in said plate. A plate 18 is attached to the upper part of the plate 15 and has its lower edge beveled, and extends across the slot 16 and serves to hold the lever 6 under certain operating conditions and a throw-lever 19 is also pivoted to the frame 1 as shown at 20, and the inner end of the lever carries a roller 21 which engages the hook lever 6. A rod 22 passes through the outer end of the lever 19 and has a collar 23 adjustably connected to the lower end thereof by means of the set screw 2%, the upper end of the rod being hooked, and the member 25 is connected to this hook, the upper end of this member being connected to the uprights 26 of the jacquard.

Thus, when these uprights 26 are raised, the member or cord 25 will pull upwardly on the rod 22 so as to cause the collar 28 to engage the outer end of the lever 19 and thus the roller 21 at the inner end of the lever will engage the hook lever 6 and press the same downwardly against the action of its spring 11 to disengage said lever with the plate 18 and permit the vibrator lever 29 to move to its lower end through the medium of its gravity.

A similar rod 27 is associated with the outer end of the lever 3 and a cord 28 connects the hook end of this rod 27 with the upright 26 of the jacquard. When these uprights 26' move upwardly the cord 28 will exert a pull upon the rod 27 and thus tilt the lever 3 on its pivot, and the movement of the lever 3 will impart a downward movement to the link 5 which in turn tilts the bell crank 4 and this movement of the bell crank will raise the vibrator lever 29 of the apparatus through means of the bell crank 30, the cables 31, and the hook 32 to which one of the cables 31 is connected, this hook being adjustably connected to the upper end of the bell crank by having its shank threaded and passing through said upper end with the nuts 33 on the threaded part and engaging at the sides of the bell crank.

The vibrator arm 29 carries the vibrator gear 50 which when raised by said arm as described, engages the continuously rotating gear 51 from which it is operated to in turn operate the box operating mechanism 53 in one direction by reason of the lever 52.

A stop 34 is carried by the frame to limit the downward movement of the throw-off lever 19 and the numeral 2 indicates the loom arc.

This indicator works in perfect order with the cam of the vibrator levers, and it insures the up and down movement of said lever, occurring at the proper time, with the cam, and there is but a pull on the lever 3 from the cable 28 of one inch and it is only necessary for the throw-off lever to move one-fourth of an inch in order to indicate the box. In other words, it is only necessary to pull about one inch to indicate and about one-fourth of an inch to throw the box in a different position.

As will be understood, when the jacquard machine pulls on lever 3, the hook 6 engages the plate 18 for the so-called high position of the vibrator lever of the boxes indicated. When the jacquard machine pulls on lever 19, it disengages the hook from the knife 18 for the so-called low position of the vibrator lever for the boxes indicated.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.

Having thus described our invention, what we claim as new is:

1. A box loom indicator comprising a frame, a lever pivoted intermediate its ends to the frame, means for rocking the lever on its pivot from the jacquard mechanism, a vibrator lever, a bell crank pivoted to the frame, means for connecting the same to the vibrator lever, a link connecting the bell crank to the first-mentioned lever, a hook lever pivotally connected to the bell crank and link at the point of connection of the link with the bell crank, a plate member with which the hooked lever engages, a spring for holding the hooked lever in engagement with said plate member, a throw-01f lever pivoted to the frame and having a part engaging the hook lever and means for actuating the throw-off lever from the jacquard mechanism.

2. A box loom indicator comprising a frame, a lever pivoted intermediate its ends to the frame, a rod passing through the outer end of the lever, a collar adjustably connected to the lower end of the rod, means connecting the upper end of the rod to the jacquard mechanism for rocking the lever, a throw-01f lever pivoted to the frame, a rod passing through the outer end of the frame, a collar adjustably connected with the lower end of the rod, a flexible member connected with the upper end of the rod and having its upper end connected with the jacquard mechanism, a bell crank pivoted to the frame, a vibrator lever, means for connecting the bell crank to the vibrator lever, a link connecting the bell crank to the first-mentioned lever, a hook lever pivotally connected to the bell crank at the point of connection of the link therewith, a slotted plate connected with the frame and through the slots of which the hook lever and the first-mentioned lever pass, a second plate secured to said first named plate and engaged by the hocked part of the lever, a spring for holding the lever in engagement with the knife, and a roller on the throw-oil" lever for engaging the hook lever.

3. In a box loom indicator frame, a lever pivoted to the frame and operatively connected to the jacquard mechanism, a vibrator lever, a bell crank pivoted to the frame and connected. to and actuated by the movement of the first lever, means for connecting the bell crank to the vibrator lever, a hook lever associated with the bell crank for holding the parts in adjusted highest position, and means for moving the hook lever' to inoperative position from the jacquard mechanism.
